Introduction

Have you ever noticed that WordPress loading speed decreases dramatically when you add more content to your site? This is a well know issue as WordPress is badly optimized when it comes to loading speed and resource usage. Good news is that you can change this with the help of WP Super Cache plugin. WP Super Cache is a static caching plugin for WordPress. It generates html files that are served directly by Apache webserver without the need to process resource-hungry PHP scripts. This helps to speed up WordPress and reduce resource usage. In this tutorial you will learn how to install and properly configure WP Super Cache plugin.

Step 2 — Configuring WP Super Cache Plugin

Caching feature is turned off by default, therefore you need to enable it and properly configure WP Super Cache plugin. Many different features can be overwhelming for regular WordPress users. That is why in this tutorial we will only use optimal / recommended settings. Follow these steps in order to configure WP Super Cache plugin:

  1. On the left menu press Settings and choose WP Super Cache tab.

  3. If you want to take WordPress optimization to the next level and speed it up as much as possible, click on the Advanced tab and enable these settings:
    • Cache hits to this website for quick access. This option turns on advanced caching.
    • Use mod_rewrite to serve cache files. mod_rewrite is built directly into Apache. It means that when a visitor comes to your site, only Apache processes will be executed. This option is fastest as it does not start PHP processes. If you get any errors after enabling this feature, it is possible that mod_rewrite is disabled on your server. In this case select Use PHP to serve cache files. This option generates html pages, but uses PHP to serve them. Unfortunately, it is not as fast as mod_rewrite as it invokes PHP processes, but still better than nothing.
    • Compress pages so they’re served more quickly to visitors. This feature will significantly reduce the size of your files.
